Abstract

The present study reports the rainwater composition during the monsoon of 2010 at Sikandra (Agra) an industrial site. The precipitation samples were analyzed for pH, conductivity, major anions (F-, Cl-, SO2-4, NO-3) and cations (K+, Na+, Ca2+, Mg2+, NH+4). The pH value varied from 6.5 - 8 indicating the alkaline nature of rainwater. Ratio of total anion to total cation is below 1. The results of neutralization factor show that the major neutralizing component was Ca2+. Good correlation among Ca2+, Mg2+, NO-3 and SO2-4 with one another may be due to these species which commonly occur in the soil. Good correlation of NH+4 with SO2-4 suggested that they are present in rainwater as (NH4)2SO4.
